摘要：
We have calculated polarizabilities (alpha(1), beta(1), gamma(1), alpha(2), beta(2), and gamma(2)) of Ps(-) by the pseudostate method. These parameters can be used to calculate Rydberg states of Ps(-) in the presence of an external electron with high quantum numbers N and L. They are also of importance in a system containing Ps(-) bound to a proton [PsH] and also Rydberg states of Ps(2).
